About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800S
The AirTAC SC125X800S is a double-acting tie-rod cylinder delivering 6136 N push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 125 mm bore and 800 mm stroke suit heavy linear actuation tasks where mid-range industrial force and a built-in position-sensing magnet are required.
This model features a 32 mm piston rod with M27x2 knuckle thread and PT1/2 ports. The adjustable air cushion (28 mm length) decelerates the piston smoothly at stroke ends. The integrated magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position feedback.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800S Is Used
Pallet Stop & Transfer
The 6136 N push force at 0.5 MPa positively stops or transfers heavy pallets on conveyor lines, with the -S magnet confirming end-of-stroke position to the PLC.
Heavy Part Clamping
Applies consistent, high clamping force on large weldments or castings in machining centres. The adjustable cushion reduces impact shock during rapid clamp/unclamp cycles.
Baler & Compactor Actuation
Drives the compression plate in recycling balers, using the full 11045 N force at 0.9 MPa for dense material compaction. Sensor feedback ensures complete ram retraction before reloading.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X800S the Right Cylinder?
Choose the SC125 bore when your application needs roughly 6000 N of force at standard plant air. If you can step down in force, the SC100 bore provides 3927 N push at 0.5 MPa in a lighter package; for higher force, the SC160 bore offers 10053 N at the same pressure. For this 800 mm stroke, verify that side loads are minimal or use an external guide system—the long, unsupported 32 mm rod can bend under lateral force.
To replace an existing cylinder, match five points exactly: 125 mm bore, 800 mm stroke, PT1/2 port thread, the built-in magnet (-S suffix), and your mounting accessory (basic here, so confirm your current bracket matches the F-SC125 series). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac AIRTAC SC125-160 Standard Cylinder SC125X800S FAQ
At 0.5 MPa, push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC125X800S is a double-acting cylinder and will not hold position if pressure is exhausted or the directional valve is centred. The piston can drift or drop. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
